OK Guys I will see what I can do about the screen caps ;)

As for a 5.1 Surround audio track. To be honest audio really isn't my thing, and to achieve this I would have to learn how to upmix Dolby Surround to Dolby 5.1 and then actually make the 5.1 upmix for each film which would mean spending even more time on this project when really I want to put this release to bed so I can move onto my 'Replica Technicolor I.B.' Star Wars Trilogy with Theatrical Audio.

As I understand it so long as your 5.1 receiver/decoder can handle Dolby ProLogic/ProLogicII you will get a surround experience, it wont be full 5.1 but then at the same time it wont be plain old stereo either. ;)

Sorry I haven't posted in a few days everyone. The encode looks good and I have started linking up the chapter menus work on finishing Jedi has been a bit slow as I have been busy / very tired the last few days and so I haven't had a lot of time to spend on it. :(

If anyone has got any particular shots from Jedi they would like me to post screen caps of just let me know. :) Something to tide you all over while you wait for the final release.

That's awesome.

Are you going to be putting out your 1997 set at the same time once these are done?

Another one of my 'quick updates'. The DVD Audio for ROTJ has been encoded, I dont have a surround set-up so I can't check the Dolby Surround/ProLogic encoding is working, just have to cross my fingers that it is! The DVD Video is also encoded now, although I didn't have a chance to look at it before I left for work this morning, so I will post another update when I know if its a good encode or not. :)

Assuming there is nothing wrong with the video, all I have left to do is to go through and configure the chapter menus, then I can author up the DVD and ROTJ will be done! Although this wont be the Coffret set finished as I still need to re-render the video for SW and ESB with the video calibration settings applied. These will then need re-encoding to MPEG2 and re-authoring.

So all in all I should have the whole Coffret set done in about a week or so.

This is what i would want.

The Star Wars Trilogy, the real versions from 1977-1983, as well as as the 20th anniversary special editions from 1997. On top of that a fixed release of the 2004 with the colors fixed, the audio mistakes corrected, and garbage mattes and effects glitches caused by the Lowry restoration to be corrected and repaired.

All scanned from the original negatives or best available sources at 8K resolution.

Lucas is a billionaire and fox has deep pockets, they can afford to restore these films. The upcoming blu ray set with no restoration, no fixed colors and only scanned at 1080P is an outrage.

Thanks for the tip dark_jedi, in that case I will use 256kbps. :) With this and Moth3r's answer to my question in this thread: http://originaltrilogy.com/forum/topic.cfm/LaserDisc-Dolby-Surround-Question/post/466813/#TopicPost466813 I am all set now to encode the audio. :D

Thats exactly the kind of answer I needed! Thanks Moth3r :D

I captured the audio from the LaserDiscs as 16-bit 48kHz PCM which IIRC has a bit-rate of about 1.5mbps, so I guess it would be worth doing it as 384kbps DD then. :)

I did some tests this evening when I got home from work to try and find out if the audio I have captured is stereo or matrix surround. I re-captured a small segment of the ROTJ audio using the "First 2 channels", "Second 2 channels" and "Mix 4 channels" settings in my capture software. I have then compared the waveforms at max zoom and to my eye they look identical. So I am now fairly sure its matrix surround aka Dolby Surround aka Dolby ProLogic. Which leaves me in a bit of a pickle as I don't know how to encode this to DD without it becoming stereo. :(

Hello,

I need some help identifying the type of audio on a LaserDisc set. As some of you may be aware I am working on a preservation of this set: http://www.lddb.com/laserdisc/35598/168035/Star-Wars:-Coffret-Trilogie Now according to the lddb page it says this set has "Digital Sound" and carries a "Dolby Surround" soundtrack. I am capturing these LaserDiscs with a Pioneer CLD-D925 and Canopus ADVC-55 using the RCA jacks on the D925.

The problem I am having is that I am not sure I have captured the audio properly. I have been looking around the web to find out what the speaker arrangement icon next to the "Dolby Surround" logo on the lddb page means and I finally came upon this webpage: http://www.aracnet.com/~nwolff/theater/surround.html according to this page this set could have 1 of 3 types of audio

1. Dolby Surround
2. Dolby 4.0
3. Dolby Pro Logic

At present I have only captured 2 channels of audio for the whole set. Now its my understanding that this would be correct for Dolby Surround which is 4 channels matrixed down to 2. If this is the case can anyone suggest how I un-matrix the 2 channels into 4 or how I could encode my 2 channel PCM captures as Dolby Digital Surround? However if the audio is not Dolby Surround but in fact Dolby 4.0 does this mean I am missing 2 channels of audio? If this is the case it shouldn't be a massive problem as I have noticed in the past that the capture settings on my system have an option to capture "First 2 channels" or "Second 2 Channels".

I am completely stumped, please help!

Another quick update. Rendering is complete for ROTJ, I hope to go through and put all the chapter markers in this evening, encode to MPEG2/AC3 over night and then author the DVD tomorrow evening. :)

Is there any preference with regards to the bit-rate of the Dolby Digital 2.0 AC3 file? Although my encoders default is 192kbps I was thinking of using 384kbps, or is this overkill?

Just a quick update. Capturing, Colour Calibration and Subtitling is complete and Rendering has begun on ROTJ. :)

The plot holes thicken, it now turns out Darth Maul isn't dead either. Dum Dum Daaaahhhhhhh!

Thanks for the reply dark_jedi! I just wanted to check I hadn't missed these on the usual places. :) I very much look forward to you're V3 release :D

This is just a theory / rambling out aloud, but you might get a better result if you only composite the luma channels from the GOUT/04SE and then merge this luma composite with the chroma channels from the GOUT.

Ideally what you need is a filter that can detect the DVNR smear, so that it will only do compositing where needed that way you're keeping the amount of the 04SE used to a minimum.

I was just wondering Dark_Jedi did you capture the ESB (1980)/ROTJ (1983) Theatrical 2.0 Surround audio yourself?

My preservation is of the "rare and hard to find CAV THX" one.

While I am here I may as well update you all on where I am up to. I have finished capturing all the LaserDisc audio/video for ROTJ, so now I just need to capture the VHS footage and then I will be ready to start editing it all together. Work has been a bit slow on ROTJ this past week as I have been distracted by the idea of automated GOUT colour correction/enhancement.

It took me only a few hours last night playing with a combination of colour correction filters in FinalCut after a week and a bit of failed attempts in Avisynth to get something that I feel is very close to the photos of the Technicolor IB showing at the Senator Theatre sans the over exposure. The results of the filter combination I have put together is by no means a perfect match, but then considering the source is the GOUT I am amazed how closely and consistently I have been able to match the GOUT to the Technicolor IB! Now there is still some work to be done, mostly minor tweaks to black/white levels, individual colour levels and overall saturation. Once all that is done I will be able to see just how good a result I have achieved and go from there. ;)

Not to worry colour correcting the GOUT is a side project, my main focus is still the coffret set and I am still on course to have this finished by the end of the 1st week of Feb. :)

LeeThorogood: Thanks for posting those. Wow, the Technicolor print looks so bright, vivid and lush by comparison! :)

ChainsawAsh if your question is directed at me, my answer is I don't know! I have kinda got to the end of my tether with colour correcting through avisynth!

I may give it a go in Final Cut as I am more familiar with Final Cut then I am avisynth.

I just thought I would share these with everyone. :)



















The Avisynth code for anyone who is interested

Tweak(sat=1.5).ConvertToRGB32().ChannelMixer(-18.0,62.5,42.5,55,-17.0,42.5,70.0,37.0,-17.0).Levels(10,0.98,235,0,255).ConvertToYV12().Tweak(hue=180.0,sat=1.1)

My appologies if colour correction was the wrong term to use, its just this is what my NLE (Non Linear Editor) refers to it as. :)

For those that are interested all I am doing filter wise is adjusting the input white/black levels using a waveform monitor, carefully and conservatively increasing the saturation using a vectorscope and finally fixing a CUE (Chroma Upscale Error) problem caused by the Apple DV codec.

Glad to hear! Can't wait, it'll be worth it. This is going to be released on a.b.starwars right?

Hi everyone, I have some good news and some bad news.

The good news is that I have captured 3/4 of the Coffret ROTJ, that just leaves the last side plus any VHS footage.

The bad news is there will probably be a 1-2 week delay in this set being finished. The reason for this is that I was watching my ANH DVD this week and I realised the picture looked overly dark and washed out, when I went back to the original captures it is clear from looking at them in a histogram and vector-scope that I need to colour correct the black/white/saturation levels. I have done this now however it will take about 48 hours per film to re-render the video hence the delay.

I plan to carry on with ROTJ and get that finished (I will colour correct this as I work on it) then I will go back and fix the other two. Clearly my hands off approach to filtering was too hands off!

Its funny while I know the middle one is overly saturated for some reason its the one I am most aesthetically attracted too. LOL

I tried playing around with Doctor Ms settings he posted above and after a couple of hours of messing around I kinda gave up on that method and went back to the method I was using before. I spent another few hours further tweaking the settings I already had and here are the results:








The Avisynth script for these colour settings would be;

########## Technicolor Imbibition
ColorYUV(off_u=-6,off_v=-2.3).Tweak(sat=1.1).Levels(16,1.08,235,0,255)

Great post Doctor M!

It is my understanding that the black levels boost in G-Forces script improves the contrast, I'm no expert so I don't know if this is the best way to do this, but IMO the GOUT certainly does need the contrast boost!

It is my observation that the reason the GOUT looks so washed out is down to three factors:

1. Lack of contrast
2. Excessive red levels
3. Lack of saturation

For factors 2 & 3 I have found that by reducing the red levels this improves the overall colours although they still need a slight saturation boost.

Once again my apologies for not posting any screen caps I have been somewhat preoccupied with the possible colour improvements to the GOUT as well as other real life issues.

I do have some good news however, capturing has begun for the Coffret ROTJ discs. I am aiming to have all the LD and VHS footage captured by the close of play Sunday. As long as I don't run into any problems turn around time should be about a week once capturing is done.

As always I will keep you all posted with developments. :)
